How to: Set a Thread Name in Native Code
dddd
最近在分析webkit 項目 。分享其中幾個tips!一、WTF庫WTF的詳細含義未找到出處，在webkit上找了找，大致是webkit 項目 繼承使用的之前的一個封裝庫。其中包涵了數值轉換，字符串，智能指針，線程管理，線程間同步等函數庫。從源代碼的命名來看，有多種移植版本，如以下注釋
// For portability, we do not use thread-safe statics natively supported by some compilers (e.g. gcc).
#define AtomicallyInitializedStatic(T, name) \
WTF::lockAtomicallyInitializedStaticMutex(); \
static T name; \
WTF::unlockAtomicallyInitializedStaticMutex();
二、How to: Set a Thread Name in Native Code
MSDN的釋義是To set a thread name in your program, use the SetThreadName function

12 DWORD dwThreadID; // Thread ID (-1=caller thread).
13 DWORD dwFlags; // Reserved for future use, must be zero.
14 } THREADNAME_INFO;
15 #pragma pack(pop)

17 void SetThreadName( DWORD dwThreadID, char* threadName)
18 {
19 THREADNAME_INFO info;
20 info.dwType = 0x1000;
21 info.szName = threadName;
